It pretty much does. A game that Celebrates Nintendo's Family and History should only have a fraction of Third Party characters. If this rumor is confirmed true then the Third Party Flood Gates are opened and you now have more people focusing on Third Party characters and Indies instead of Nintendo characters. Any Third Party Company will try to get their character in Smash just for advertising, which does not automatically benefit Nintendo. Third Party Companies release their games on whatever device they want, but they want the advertising potential.
If you are going to add in more Third Party characters than it ceases to be Smash Brothers and more Nintendo vs. Namco vs. Capcom vs. Sega, which is not the point of Smash Brothers.
How many characters are in Smash Bros right now? More then 50 if we count Lucas/Ryu/Roy. How many of those are 3rd party characters? 3. 4 if you count Ryu.
Around 1/13 of the current cast is made up of third party characters. Assuming they added ONLY third party characters from here on out (Not happening. Even if they do hit that number in the far future, they'd have plenty of Nintendo characters in between) They'd have to add around 7-8 more just to make up a 5th of the roster, and even then there are 50 Nintendo characters to counterbalance them.
Who have we gotten so far? Snake, Sonic, Megaman, Pacman, and most-likely-soon Ryu. These characters are better known and loved then the MAJORITY of the Smash Bros cast.
My point still stands that Smash is capable of being 40% non-Nintendo, against being a celebration of Nintendo's History and Family.
Smash Bros is a game about Nintendo's history, and whether purists like it or not, other companies are part of that history.
Guys, calm down. You're making the assumption that Ryu is guaranteed to be in the game, and the files are brand new and not files from some old beta.
The files were patched into the game YESTERDAY. These aren't "Old beta files", they weren't present in the previous versions of Smash Bros.
I doubt that they were intentionally patched in, but the fact of the matter is that victory themes for Ryu and Roy were ADDED into the game POST RELEASE. This isn't some text leak or person claiming that they're dad works for Sakurai, it's content FOUND IN THE GAME.
No, I suppose Ryu and Roy aren't 100% guaranteed, but they are more likely then any other DLC character at this point in time.
